Pd‐based catalysts supported on cerium‐zirconium (CZ) oxygen storage materials (OSM) have emerged as promising candidates for the catalytic oxidation of CH4 and CO. However, achieving efficient and stable treatment of CH4 and CO in exhaust gases with Pd‐based catalysts remains a long‐term challenge. To address this, we propose a straightforward strategy of doping the supports with Cu to enhance the catalytic performance of Pd/Ce0.4Zr0.5La0.1O1.95 catalysts. Performance tests revealed that the catalytic activity of the Cu‐doped catalysts significantly improved, with T90 (CH4) decreasing from 418 to 301 ℃ and T90 (CO) decreasing from 141 to 113 ℃. Notably, the copper‐doped catalysts exhibited enhanced water and sulfur resistance while maintaining excellent thermal stability. The CO conversion decreased by less than 2% after a thermal deactivation experiment lasting over 100 hours. The reduction in particle size and the increase in specific surface area due to copper doping are key factors contributing to the improved total oxygen storage capacity (OSC). The main reasons for the increase in total OSC are likely the reduced particle size and increased specific surface area.
